I’m also finding this high cpu usage to be the case. I’ve tried some different options/tweeks but I still have about 24% usage at best. This becomes unusable when I have to use various sounds at the same time. Here in Spain, we play many Hispano-american music (“latin cumbias / merengues”) and mainly with cumbias, the left hand is playing counter piano and the right is playing accordion/flutes/melodies so my issue is that I’m playing Pianoteq + 1 / 2 / 3 sounds at once… thus raising the CPU usage to about 30 or 40% on occasions…
Can anyone advise me on how to reduce this in any way?
I was considering opening a second instance just for piano so as to have it on it’s own core but I seem to remember @dhj saying that a second instance doesn’t guarantee it using another cpu core..
I think the more correct statement is more likely to be “Pianoteq is much better with RAM than any other VST piano.”
This would make sense because most pianos are sample-based. Many of them can use a lot of memory/ram.
PIanoteq is physically modeled. So, it uses very little ram.
I would not be surprised if Pianoteq, however, uses more CPU. It is basically a type of synthesis. So, physically modeled plugins tend to use more CPU. While sample-based plugins tend to be more ram intensive. (If course, effects, etc. can have a big effect on CPU too).
So, if CPU is the concern, it makes sense to me that Pianoteq uses more CPU (but less ram) than sample-based piano libraries. If ram is not an issue (I have more of a concern with RAM than CPU for the most part), then one of the many (excellent) sample-based pianos may be a better option,
Well, I try to keep the CPU around 20% at most because of the high temperature the laptop reaches even when it’s kept at 20%. And I feel more comfy keeping the GP CPU as low as poss because I don’t fancy finding myself with crackles and pops.
Yes, I’ve lowered it to 16 notes, 44,1KHz & is 192 Samples
